Toyota Axle Widths
Toyota axle widths! If you want to do an axle swap, you gotta know ‘em.
Here are all dimensions and factoids you need like spring perch width, pinion drop, and brake type.
Let's get to it!

- There are different pinion flanges. You can fix this by using a 27 spline triple-drilled flange (very common) or a 29 spline triple-drilled flange (not factory until early 2000s, but used in many aftermarket Toyota ring and pinions).
- The differential hump might be in the way. For instance, FJ60 axles have the hump slightly further out than a 40’s. A 40 getting a 60 axle swap usually has some minor issues to properly attach the spring and keep the spring perch low to the axle.
- Land Cruiser rear axles are all offset to the passenger side. Minis and 4Runners have a front passenger offset and are centered in the rear. If you decide to run 60 axles in your mini, your driveshaft will run from the center of your truck to the passenger side. This will run perfectly fine, since your driveshaft does not know where up is, but it might make your driveshaft a wee bit more vulnerable.
- For Toyota trucks and 4Runners, there is one front axle width, and it is not wide. This is solved with:
- Spacers - Not great, sometimes illegal, and may wear out your front end sooner.
- IFS hub swap - Gets you about 3” more width.
- Aftermarket axle housing - Requires a longer “long-side” inner axle shaft.
- An FJ80 front axle - Read more about the ultimate Toyota SAS axle.
- Brakes may not match master cylinder. Brake master cylinders with small bores can’t move enough fluid for large, multi-pistoned calipers. If you put FJ60 axles into your Suzuki Samurai, you’ll need a larger bore master cylinder. While this isn’t a big issue with most Toys, swapping axles means you may be doing other stuff that makes your brakes work harder, so think about a master cylinder swap.
- Wheel Mounting Surface: This is the surface on the axle that the wheel sits flat on. This is usually a drum brake drum, disc brake disc, or a wheel hub. You'll often see this used in a "WMS to WMS" measurement, which is the same as "axle width".
- Wheel Mounting Flange:This is the same as WMS.
- Independent Front Suspension: Instead of a solid axle, that moves as one unit, each side articulates independently.
- Spring Perch Center: While coil axles do have spring perches, this is usually used when talking about leaf-sprung axles. Knowing this tells you whether you can bolt in an axle or if you'll need to do some fabrication. Some axles (like all Toyota axles) have welded on perches. You can cut them of and put them anywhere on the axle. Some other axles (like some one tons) have cast perches, which means you'll (usually) be adjusting the width of your leaf springs instead of the perch placement.
- Track width
- Don't use this term! Why? As far as we can tell, no one knows what it means. We have seen it used to describe the measurements from: center-of-tire to center-of-tire, WMS to WMS, outside tread to outside tread, and rear width only (even when the front is different). Track width is useless for our purposes.
We’ve compiled a list here of axle widths, spring perch center
measurements, and some brief info about the axle setup. Take a look at some acronyms and definitions at the bottom of the article if you don't know what something is.
Toyota Axle Swap Issues
If you're here, you're probably thinking about an axle swap. Figuring out the the width of a particular Toyota axle is only the first step; there are always some other things to consider. Most of the below axles have been swapped into all the other vehicles in the axle width table (eh…maybe not the IFS stuff). Issues that come up are usually:
About These Measurements
We think this is the most comprehensive list of Toyota axle widths on
the Internet…but don’t count on them.
Here's the deal:
We did our best compiling them
and expect that most of them are within a 1/4” of the actual
measurement. These seem to be somewhat difficult measurements to get
due to measuring technique and stuff being in the way (like the diff and
diff cover). We were surprised at the different measurements stated
for the same vehicle in various spots.
Toyota Axle Widths
|Vehicle models||Front or Rear||Years||Suspension Type||Width, WMS to WMS||SPC to SPC||Offset||Notes|
|Toyota pickup/mini and 4Runner||Front axle||1979-1985||Leaf||55.5"||29"||Passenger||With stock hubs.|
|Front axle||1979-1985||Leaf||58.25"||29"||Passenger||With IFS hubs.|
|Rear axle||1986-1989||Leaf||58"||39.6"||Center||IFS front.|
|Rear axle||1986-1995.5||Leaf||58"||39.6"||Center||IFS front. We've found that the axle shafts from the coil rear will not fit this housing as they are too long.|
|Rear axle||1990-1995.5||Coil||58.5"||NA||Center||IFS front. Axle shafts are 7mm shorter than late 80s leaf axles.|
|Toyota pickup/mini 2 wheel drive||Rear axle||1979-1995||Leaf||56"||Center||5 lug|
|Toyota T100||Front axle||1993-1998||IFS||65"||NA||Passenger||IFS|
|Rear axle||1993-1998||Leaf||66.75"||Center||IFS front|
|Toyota Tacoma and 4Runner||Front axle||1995.5 +||IFS||60.75"||Passenger|
|Rear axle||1995.5 +||Coil||60.75"||NA||Center||4Runner only. IFS front. Some of these Toyotas have the factory e-locker.|
|Rear axle||1995.5 +||Leaf||60.75"||Center||Tacoma only. IFS front. Some of these Toyotas have the factory e-locker.|
|Toyota Land Cruiser FJ40/FJ45/FJ55||Front axle||All||Leaf||55.7"||27.2"||Passenger|
|Toyota Land Cruiser FJ60 and FJ62||Front axle||All||Leaf||58.9"||31.6"||Passenger|
